The problem blockchain companies have is that at some level they need to interact with the traditional financial system to make money. That means dealing with legal entities in various states and dealing with lots of pesky regulations that those states have around investing and transacting.
Basically, in most civilized places, if you want to be a bank there are some rules to be taken into account. That's why stablecoins are so hard to do because as soon as you start transacting, you are exposed to those rules because you basically become a bank like entity. So, authorities wake up and start paying attention as soon as you do that.
The projects you name are interesting because they are all based in the US and are being built with good old investor cash raised from the usual suspects (i.e. VCs). So, they have share holders and are operating under US law. Basically all three are really talking about building similar things but as an outsider you have to wonder who wins if their token business is successful: the share holders or the token holders?
There's a bit of friction here between the marketing on one hand projecting some kind of utopian decentralized thing and the obvious desire of the investors to turn this thing into a very centralized money funnel straight into their pockets. The reality is of course that these are companies and not charities and the reason investments are so high is that they are looking to tap into significant streams of cash. Just like banks.
